Struct Parallelism

Source

pub struct Parallelism { /* private fields */ }

Expand description

Specifies data parallelism settings.

Implementations§

Source §

impl Parallelism

Source

pub fn new(num_thread_pools: usize, threads_per_pool: usize) -> Parallelism

Creates an instance of Parallelism.

Source

pub fn new_with_cpus(available_cpus: usize) -> Parallelism

Creates an instance of Parallelism using available cpus as given.

Source

pub fn available_cpus(&self) -> usize

Amount of total available CPUs.

Source

pub fn thread_pool_execute<OP, R>(&self, idx: usize, op: OP) -> R
where OP: FnOnce() -> R + Send, R: Send,

Executes operation on thread pool with given index. If there is no thread pool with such an index, then execute it without using any of thread pools.

Source

pub fn thread_pool_size(&self) -> usize

Returns number of non-default thread pools. Returns zero if only default thread pool is used.
